Pengaruh Variasi Beban terhadap Faktor Kekuatan Rangka Sepeda dari Bahan AISI 1035 Steel (SS) dengan Simulasi Solidworks
Get PDFThis research aims to investigate the impact of load variations in the range of 140 Kgf to 240 Kgf on the strength factor of bicycle frames made of metal material, namely AISI 1035 Steel (SS), through Solidworks simulations. The parameters used in the simulation evaluation are the load or force that occurs, stress or von Mises, displacement and factor of safety. The main focus of the research is to evaluate the structural response of the bicycle frame to these load variations and identify the most optimal loading, taking into account a safety factor of 2.5 applied to the design. The Solidworks simulation method is used to analyze the maximum stress that occurs (114.3 N/mm2) and maximum displacement (0.245 mm) in the bicycle frame. This simulation includes the application of gradual loads to a bicycle frame model, and stress and displacement calculations are carried out in detail. The results show that the most ideal loading occurs below 220 Kgf, indicating optimal structural stability and safety. The conclusions from these findings provide deep insight into the performance of bicycle frames in the face of certain load variations. Potential implications include the development of more efficient and safer bicycle frame designs, contributing to increased safety and comfort for bicycle users
Penerapan Teori Penetrasi Sosial dalam Komunikasi Virtual (Studi Kasus pada Komunitas Penggemar BTS atau ARMY)
Get PDFThe fan community, particularly in Korean music culture, commonly referred to as K-Pop, is flourishing in tandem with the evolving times. Beyond being a platform for sharing common interests, fan communities have become a means for interaction, discussion, and the formation of friendships. The progression of time, facilitated by digital technology, further supports this through the creation of fan communities engaging in virtual interactions, predominantly on social media platforms. The objective of this research is to explore the dynamics of virtual communication relationships within the BTS fan community (ARMY) using the Social Penetration Theory. This theory is employed to comprehend the process of interpersonal relationship development within virtual communities. The research adopts a qualitative research method with a case study approach, utilizing in-depth interviews and observations as data collection techniques. The study involves 15 active members of the BTS fan community who interact on social media fanbase platforms. The research findings shed light on the understanding of how BTS fan community members establish and foster a sense of intimacy through virtual communication, exploring the application, influencing factors, and stages of these relationships. The theoretical and practical implications of this research, supported by previous studies, can provide guidance for community managers and other researchers, contributing to the development of the Social Penetration Theory in the context of virtual communication.Komunitas penggemar, utamanya dalam budaya musik Korea atau biasa disebut K-Pop semakin berkembang seiring zaman yang semakin berubah.

Analisi Kemampuan Berpikir Kritis Siswa Pada Pembelajaran Optik
Get PDF: Optics is a branch of physics related to complex and abstract daily life technology. Critical thinking skills can make a very meaningful contribution to students in understanding abstract material such as optics. Therefore, this study aims to describe students' critical thinking skills in the context of optics learning. Descriptive method with qualitative approach was applied to 108 students of class XII MIPA. The research instrument consisted of 5 description questions. The results showed that the average critical thinking ability of students was 55.28 (medium category). When viewed from each sub-matter, the percentage of students who fall into the low critical thinking ability category is 53.7% (light reflection material) and 54.6% (light refraction material). In a more in-depth analysis, the percentage of students' critical thinking skills on each indicator also tended to be higher in the low critical thinking ability group, with values of 66.7% (interpretation indicator), 71.3% (analysis indicator), 65.7% (inference indicator), 86.1% (evaluation indicator), and 80.6% (explanation indicator). The implications of the results of this study indicate the need to apply learning methods that can train students in solving problems in everyday life that are general and complex, such as PjBL and the STEAM approach.Optik adalah cabang ilmu fisika yang berkaitan dengan teknologi kehidupan sehari-hari yang kompleks dan abstrak.

Pengembangan Metode Pengajaran Dialogis dengan Pendekatan Hadap Masalah Paulo Freire sebagai Upaya Mewujudkan Kemerdekaan Belajar
Get PDF‘’Independence of Learning†from the MBKM concept is often associated with Paulo Freire's critical pedagogy. This research and development (R&D) seek to design and test dialogic learning strategies/methods using the ADDIE model (analyze, design, develop, implement & evaluate). The product trial consisted of expert assessment and field trial through formative evaluation (one-to-one, small-group & field trial) which was conducted by 30 participants. Data collection techniques include filling out questionnaires’ interviews, observation and documentation. Quantitative data analysis uses descriptive statistics with the help of IBM SPSS 26 software. The qualitative data analysis uses the help of Atlas.Tiversi 9 qualitative data analysis software. Based on the results of the field-test evaluation with a percentage of 90%, it can be concluded that the dialogical teaching method is very feasible. Three main themes from the qualitative data were (a) the relationship between the teaching method and students' responses, (b) students' readiness for critical learning and (c) the positive effects of problem-facing learning. Prospectively, our design is promising to be used as a teaching method in future MBKM curricula
Collaboration Skills in Vocational Schools in The Information and Communication Technology (ICT) Sector
Get PDFIn 2018, the technology, business and ICT (information and communication technology) sectors were the sectors that received the most new students at the vocational school level. Jobs in the ICT sector are one of the sectors that are really needed in Indonesia. There are more job vacancies in the ICT sector for vocational schools than for high schools. However, in the 2015-2019 period, the number of ICT sector workers with high school graduates was higher than vocational school graduates. The soft skill that is most needed in ICT sector jobs is collaboration. The main objective of this literacy study is to describe learning methods to improve collaboration skills in vocational high school students in the ICT field. Systematic literacy study using the PICOC framework is the method used. The results of this literacy study are in the form of descriptions related to: 1. The concept of collaboration; 2. Challenges and obstacles; 3. Learning activities to improve collaboration skills. It was found that problem-based learning (PBL) can improve collaboration abilities. To be suited to the world of work, it is necessary to integrate the Scrum model to develop vocational school students' collaboration skills in the field of ICT

Studi Kritis: Pembelajaran Toleransi dalam Buku Ajar Pendidikan Agama Islam dan Budi Pekerti Sekolah Dasar
Get PDFIslamic Religious Education and Ethics textbooks, hereafter written as PAI and BP, are vital elements in instilling character values, including tolerance in schools. However, cases of intolerance still occur frequently in Indonesia and this is often associated with religious education in schools. This research seeks to reveal the proportion of PAI learning materials and how the learning content of tolerance in PAI and BP textbooks. This research uses a qualitative approach with a literature study method that analyzes the content of PAI and BP textbooks published by the Ministry of Education and Culture 2013 Revised Curriculum 2013 (Grades II, III, V, and VI) and Independent Curriculum (Grades I and IV). Data analysis techniques in this study are 3 stages, namely data reduction, data display, and data verification. The results showed that the proportion of material in PAI and BP textbooks is dominated by moral material that is in line with the objectives of Islamic religious education, then in the textbook there are 4 categories of tolerance, namely: (1) tolerance in belief and worship; (2) tolerance of coexistence with other religions; (3) tolerance in inter-community relations; (4) internal tolerance of Muslims packaged with interesting illustrations, especially in independent curriculum books
